Time frequency signal analysis and processing toolbox update 6.2: An enhanced research platform with new advanced high-resolution TFDs

Abstract

This paper describes the advancements, updates and improvements made in the new Time Frequency Signal Analysis TFSAP toolbox as compared with the previous TFSA toolbox version. The updates and improvements done in TFSA toolbox are in-line with the latest research done in recent few years in the field of time-frequency based signal analysis. TFSA Toolbox has proved in the past to be an efficient and popular tool for analyzing non-stationary signals. The new TFSAP Toolbox is an updated Matlab toolbox that extends the functionality of previous TFSA toolboxes. It provides additional options for generating new time-frequency distributions, and synthesizing a signal from its time-frequency distribution. It also includes options for analyzing real-life signals such as biomedical, speech and radar signals. Several demo scripts are also included in the new version to demonstrate the main functionality of the toolbox and to coach new users to use TFSA toolbox for advanced signal processing applications dealing with non-stationarities. The new version is renamed TFSAP 6.2; it can be downloaded for free as a service to the community.
